How'd you like to get paid to lose weight? Financial incentives can help improve your odds of dropping pounds, according to a new study.
Researchers at the Mayo Clinic followed 100 Mayo employees over the course of a year as they took educational classes on how to eat healthy and lose weight.
The employees were broken up into several groups - some of which got financial incentives to shed the pounds and others that just got the classes.

There's a lot said about how to lose weight. As it turns out, a lot of what's said may not be true.
To sort fact from fiction, a group of doctors and nutritionists researched the medical evidence behind common claims and presented their findings Wednesday in the New England Journal of Medicine.
Beyond academia, however, the doctors and nutritionists also have deep ties to industry, receiving grant support and consulting fees from food, drug, and diet companies, raising questions about how wide a net of inquiry the authors were willing to cast.
Still, here are what the researchers say are the seven myths about obesity:

Losing weight may not be just about WHAT you eat but WHEN you eat it, according to a new study. Participants in the study who ate a bigger meal later in the day lost less weight than those who ate earlier.
Study authors Marta Garaulet and Dr. Frank Scheer, director of the medical chronobiology program at Brigham and Women’s Hospital in Boston, followed 420 people in Spain during a 20-week weight loss treatment program.
The participants were split into two groups – early eaters who ate lunch before 3 p.m. and late eaters who ate lunch after 3 p.m. In Spain, lunch is the biggest meal of the day, comprising about 40% of a person’s daily calories.
The early eaters, on average, lost 25% more weight than the late eaters over the course of the study, according to Scheer.

With all the talk about obesity in America, you might be surprised to know that most people are pretty good at losing weight.
Weight loss programs have proven effective in helping people drop pounds. But keeping them off is another story.
Studies have shown that overweight participants typically give up their newly learned health habits and regain 30 to 50% of the weight they lost within one year, even if they participate in a post-weight loss maintenance program.
“There’s something we’re missing in terms of what it takes to maintain our weight,” says Michaela Kiernan, an expert in behavioral weight management at the Stanford Prevention Research Center.

Trainer Jillian Michaels is headed back to "The Biggest Loser" next year and she's bringing a new challenge with her. The weight loss show is adding child participants for the first time in its 13-season history.
At least three teens between the ages of 13 and 17 will be included in the competition. They will work with trainers, nutritionists and child obesity experts to drop pounds just like the adult contestants on the ranch. Unlike the adults, however, they will not be up for elimination each week.
“As a former overweight teen, I know firsthand how dramatically weight issues can affect every aspect of a child’s life,” Michaels said in a statement from NBC. "Having recently become a mother of two, I am more passionate than ever about helping empower children and families with the information and resources they need to live a healthier life.”
More than one-third of children and adolescents are overweight or obese, according to the Centers for Disease Control and Prevention. NBC hopes featuring children on the show will "inspire kids all over the country to get healthy."

Cutting back on calories is the cornerstone of any successful weight-loss plan, but as dieters can attest, that's easier said than done.
So it's encouraging to learn that three simple strategies can provide a boost: Eat regular meals, write down everything you eat, and avoid restaurants and takeout at lunchtime.
These three habits were each linked to greater weight loss in a new study of 123 overweight and obese middle-aged women, all of whom managed to shed at least a few pounds over a one-year period.

Some people who suffer from chronic weight issues may soon get some help from a pill.
The U.S. Food and Drug Administration Wednesday approved Belviq, or lorcaserin hydrochloride, to be combined with a reduced-calorie diet and exercise, for treatment of chronic weight problems.
Specifically, the FDA says, it is approved for overweight or obese adults who have one or more medical conditions due to their weight, such as high blood pressure, type 2 diabetes or high cholesterol.

Older women who don't get enough vitamin D may be slightly heavier than those who do.
A Kaiser Permanente study, published online in the recent issue of the Journal of Women's Health, looked at more than 4,600 women aged 65 and older for a four and one-half year period. Researchers found women with low levels of vitamin D in their blood gained about two pounds more than those with adequate levels of the vitamin.
So what’s the big deal, you ask?

Certain patients who undergo weight-loss surgery may have a heightened risk of developing a drinking problem, but the risk is only apparent two years after the procedure and only with one type of surgery.
A new study, published today on the website of the Journal of the American Medical Association, examined the drinking habits of almost 2,000 obese adults before and after bariatric surgery.
Before the surgery, 7.6% of the study participants met the criteria for an alcohol-use disorder. One year after the procedure that number had actually declined slightly, to 7.3%, but by the end of the second year it had risen to 9.6% - a 57% increase from the pre-surgery rate.
